Explain How A Light Bulb Make Light And Thermal Energy at Charles Gilley blog

Explain How A Light Bulb Make Light And Thermal Energy. The light bulb works by heating a filament inside a glass enclosure. In fact, a typical light bulb produces perhaps 15 lumens per watt of input power compared to a. As current passes through the. Different materials have been used for the filament over. Incandescent light bulbs are devices that convert electricity into light by heating a filament, using electric current, until it emits electromagnetic radiation. Modern incandescent light bulbs (see figure 1) are highly inefficient, with about 90% of. In these bulbs a tungsten filament inside them. A light bulb is an energy conversion device that converts electrical energy into light. The production of visible light via thermal radiation is exploited in incandescent light bulbs. Most of the energy that goes into an incandescent bulb is lost as heat. This wastes a lot of electricity. The heat from the filament produces light. These different kinds of bulbs work on different mechanisms where the wastage of energy as heat energy is less and a more significant part of electrical energy is converted into light energy.
